AdvertisementThe story of ozone and public health casts scientists as vigilant and courageous heroes on a quest for understanding in the service of the public good. Society must again turn to scientists for solutions if we are to restore reason and calm to the crises facing humanity — from COVID-19 to climate change. As with ozone, the scientific understanding is definitive and has been for years: Carbon dioxide emissions cause climate change. Scientists have been deciphering the ocean’s role in global climate, finding new tools to forecast hurricanes and droughts, and documenting the impact of climate change on fisheries, agriculture, and wildlife. By definition, science seeks to avoid bias, remain independent, refute falsehoods, and seek answers based on evidence, reason, and consensus.
